| 摘 要： | 研究了不同条件下TiO2和Fe2O3在合成渣中被碳还原时的发泡过程．计算了该发泡过程的发泡系数、消泡系数、平均发泡寿命、发泡强度和消泡过程开始的时间．用熔渣发泡参数定量地讨论了温度、TiO2加入量和初渣中TiC的含量对熔渣发泡过程的影响，发现当初渣中TiC的含量和TiO2加入量较多时，在发泡时会产生二次发泡现象．

| Abstract: | The foaming processes originated from reducing TiO2 and Fe2O3 by carbon in the synthetic slag were investigated under different conditions in laboratroy. The formation and rupture coefficients, average foam life, foam intensity and beginning time of the rupture foaming process were determined by means of experimental results. The influence of temperature, TiO2 added in synthetic slag and TiC content in original slag on these foaming processes were discussed through the foaming parameters. It is found that the secondary foaming phenomena in twice can take place when the original slag contains when more TiC and more TiO2 is added. |
